王安忆小说少女精神成长主题的自传体色彩

王安忆个人几十年的人生体验对她的创作产生了不容忽视的影响,忧伤的童年体验、青涩的成长经历是其创作的源泉和表现内容。将王安忆在小说中对少女童年、少年、青年阶段成长经历的书写与其个人经历相结合,可以发现王安忆对少女精神成长的书写带有浓厚的自传体色彩。     

The role of scaling up research in designing for and evaluating robustness

One of the great strengths of Jim Kaput’s research program was his relentless drive towards scaling up his innovative approach to teaching the mathematics of change and variation. The SimCalc mission, “democratizing access to the mathematics of change,” was enacted by deliberate efforts to reach an increasing number of teachers and students each year. Further, Kaput asked: What can we learn from research at the next level of scale (e.g., beyond a few classrooms at a time) that we cannot learn from other sources? In this article, we develop an argument that scaling up research can contribute important new knowledge by focusing researchers’ attention on the robustness of an innovation when used by varied students, teachers, classrooms, schools, and regions. The concept of robustness requires additional discipline both in the design process and in the conduct of valid research. By examining a progression of three studies in the Scaling Up SimCalc program, we articulate how scaling up research can contribute to designing for and evaluating robustness.     

基于Q-learning的飞行自组织网络QoS路由方法

针对无人机自组网等高动态飞行自组织网络中,网络拓扑的快速变化导致通信链路断裂和路由重建频繁的问题,研究一种基于Q-learning的QoS(quality of service)路由方法.该方法以Q-learning强化学习框架为基础,将邻居节点数量、链路持续时间和链路可用带宽作为路由度量信息,设计一种提供QoS保证的...     

“弱者优先”训练原则中“薄弱环节”与“关键环节”的判定方法

在运动训练实践中,要贯彻和执行好“弱者优先”原则,首先要正确判定动作模式的“关键环节”与“薄弱环节”。为此,以原地纵跳动作为实例,阐述了判定“关健环节”与“薄弱环节”的具体方法。

The role of technological catch up and domestic market growth in the genesis of emerging country based multinationals

The paper presents a model that evaluates how upgraded technological capabilities of emerging country based multinationals (EMNCs) and an increase in the domestic market size of large emerging countries affect value chain location choices and the competitiveness of emerging country based firms versus advanced country based ones. The model shows that, even without possessing a competitive advantage in terms of technology and/or brands, EMNCs from large or rapidly technologically advancing countries can become dominant players in the global system. The model highlights the central role of firm level technological intensity and product differentiation in determining the location of value chain activities as well as defining organisational boundaries. Empirical analysis of the location choices of the world's top multinationals from large advanced and emerging countries in 2010 supports the model's predictions.     

一个超图嵌入问题的多项式时间近似算法

把定义在一个圈上的超图的每个超边映射为这个圈的一条路,每条超边的顶点均在对应的映射中,要求使圈中的任一边经过的路的最大次数最小,称此问题为超图在圈中的最小嵌入问题.将此问题归结为最近串选取问题,从而证明该问题存在多项式时间近似算法.

教育戍边：兵团屯垦戍边在跨越式发展阶段的新形式

＂屯垦戍边＂是兵团的历史使命和根本任务,随着兵团经济社会的发展及国内、国际形势的不断变化,传统意义上的＂屯垦戍边＂已难适应边疆的长期稳定与发展。＂屯垦戍边＂向＂教育戍边＂的转变是经济社会发展的结果,＂教育戍边＂是实现稳疆、富疆的途径之一。文章从＂屯垦戍边＂向＂教育戍边＂的转变的历史背景、作用和意义及其实现的途径等方面进行分析与思考。
